Should i flush or should i feed?

Looks like the start of gnats attacking your plants. Do u see any?? If you do use nematodes super easy like 15dollars. Gone and sray gone as ling as your medium is moist. Otherwise id say its hungry but to be honest looks like gnats. If ur using organics then half the amount your using and feed. If salts drop ur ppm to 700 and feed make sure to add cal mag first then your nutes then ph down or up whicheber u need to get if using salts a 6.o if using organic bottle nutes like biobizz then 6.2 to 6.4 6.3 is safe zone

Depends what your after pal I would personally keep them in veg a tad longer if you have the overhead space to fill it you have done good training on them so Id keep going :) Maybe flush for a few days but bottle leaves fading yellow is often a sign she is not getting enough Nitrogen so maybe try and increase the feed a little bit and see how you go other than that your doing a great job.

Thx for replies :)
